Problems solved by technology

The disadvantages of this method are: the production cycle is prolonged, the production cost is increased, and it is not conducive to large-scale practical production applications.
However, if the above-mentioned method first mixes the biomass material with other raw materials, and then carries out molding and carbonization treatment, there will be problems such as difficult control of the process and uneven pore formation, so the biomass material can only be carbonized first, and then Shaping and subsequent sintering after mixing with the required raw materials

Embodiment 1

[0034] Embodiment 1, the preparation method of biomass carbonization molding material (brick):

[0035] Bamboo (with a moisture content of about 10%) is pulverized to obtain a powder with a particle size of 100 mesh, and then mixed uniformly with an appropriate amount of clay (with a moisture content of about 10% and a particle size of 200 mesh) to obtain a mixed material; the above two Their weight ratio is controlled at 15 / 85 (that is, the weight content of bamboo in the mixed material is 15%, and the weight content of clay in the mixed material is 85%). Then add water accounting for 10% of the total weight of the mixed material, and mix and stir for 2 hours. The resultant is injected into a mold and pressed into a mold (for example, pressed into a biomass carbonized brick of 600×600×200 mm), and dried at room temperature for 24 hours after demolding (moisture content ≤ 8%); After burning for 8 hours and cooling to room temperature, the final biomass carbonized molding mate...

Embodiment 2

[0036] Embodiment 2: Change the temperature of the smoldering treatment in Embodiment 1 to 1200° C., and the rest are equal to Embodiment 1.

Embodiment 3

[0037] Embodiment 3: Change the temperature of the smoldering treatment in Embodiment 1 to 1300° C., and the rest are equal to Embodiment 1.

[0038] The 1000 times scanning electron microscope photos of the carbonized decorative bricks prepared in the above-mentioned embodiments 1 to 3 are as follows: Figure 1 ~ Figure 3 shown;

[0039] according to Figure 1 ~ Figure 3 We can know that: within the range set by the present invention, the higher the sintering temperature, the denser the material.

Abstract

The invention discloses a preparation method of a biomass carbonization molding material. The preparation method successively comprises the following steps: 1) crushing natural biomass materials so as to obtain powder of which the sieving rate is equal to or larger than 100 meshes; 2) adding clay to the powder, uniformly mixing the clay and the powder so as to obtain a mixed material, wherein the powder accounts for 10-45% of the total weight of the mixed material, and the clay accounts for 55-90% of the total weight of the mixed material, adding water accounting for 5-30% of total weight of the mixed material to the mixed material, and mixing and stirring the mixed material with the water; 3) injecting the obtained mixture in a mold to perform compression molding, after demolding, drying the demolded object until the moisture content is equal to or smaller than 8%, performing smoldering treatment under 800-1300 DEG C and the anoxic condition of sealing for 0.5-10 hours so as to obtain the biomass carbonization molding material. The carbonization molding material prepared by adopting the preparation method disclosed by the invention not only has good mechanical strength, but also has the characteristics of being green and environment-friendly, capable of purifying air / water quality and the like, and adsorbing harmful substances in the air / water.

Description

technical field [0001] The invention relates to a method for synthesizing green and environment-friendly carbonized molding materials in one step by using biomass materials as carbon sources. Background technique [0002] Building materials and decoration materials used in daily life often volatilize and release formaldehyde, benzene, radon and other harmful gases and radioactive substances, which seriously threaten people's health. How to provide a healthy and comfortable living environment for human beings has attracted more and more attention. With the increasing awareness of people's health and environmental protection, it is of great practical significance to develop green and environmentally friendly building materials and decorative materials. [0003] my country has a vast territory and is also a large agricultural country, which produces a large amount of biomass materials (wood bamboo, straw, fruit shell, bark, etc.) every year. This kind of biomass material has ...
